Where is the alpha symbol?

Excuse me, but I was wondering if you could assist me with something. I'm currently looking for the alpha symbol, and I'm having a bit of trouble finding it. Do you happen to know where it might be located? I've checked a few places already, but I haven't been able to locate it just yet. It's a rather important detail for what I'm working on, so any help you could provide would be greatly appreciated. Thank you in advance for your time and assistance.
